rlfhis invention relates to a linger bowl attachment, the object of `which is to prevent using water or other fluid insaid howl or receptacle which. has been previously used. fthe organization ol' the invention con'iprises a disk which is detachably connected to the inner wall ot the receptacle. Means are provided which coact with an orifice 'in the disk which allow the water or otherI fluid te Aflow trein one compartment of the device to the other7 and where d means have been used their positions indicate to the user that the water or other l'luid has been used.

lhe accompanying drawings exemplify the invention and in which Figure l is a vertical axial cross-section oii a linger bowl, with the invention in part axial section and part in lull lines; Fig. 2 shows a fragmentary plan view oit the linger bowl and in vention; lFig. S represents an enlarged tragmentary portion et Fig. 2 and 4f shows a top plan view of some details.

rllhe linger bowl is indicated at and has fastened to the inner lace ott its side wall the supporting brackets 2l. ik disk is supported on the brackets The said disk has 'formed therewith the annular recess with the annular groove 2li.

it follower ring with the annular groove 27 is bolted to the disk by means ot the screws 28. ik pliable packing ring preferably o't rubber is clamped in the said grooves Qd and QT and bears watertight against the inner lace of wall oli the bowl 20. T he disk 22 has an orilice 33 preferably in the vertical axial center thereoli. in annular pliable packing ring 3l preferably of rubber bears up against the bottom tace ot the disk Q2. ik pair ot clamping rings 31') and 3G are fastened to the disk and hold the packing ring 34- in place. rllhe said packing ring Sil with its clamping rings 35 and 8G are concentric with the orifice t bracket Ll0 is fastened to the bottom tace et 'the disk 22 and has hinged to it the trap door 4l which latter has 'formed therewith the latch lug d2.. A spring latch is shown to comprise a spring which carriesthe push button L.hll and the latch. boekt-l5. it stop bracket is instened tothe lower tace of the disk 22 and clamps to the Alatter` one end et the spring afi; 'lll-ie said la'ackethas :termed therewith the protectingleg 52. il. spring 53 hasone end liastenedto the bracket l0 and the other end bears on the trap door dell l j j ik flexible pusher carp` is ilfastened" to the dis C 22 over the push button elli; il handle 56 is connected tothe hinge brackets 57 which latter in turn` are attached to the disk 2Q. rll`he said disk Q2 when in place in the tinger bowl divides the latter inte the clean water compartment 5d and the soiled water compartment 59 rlo prepare the invention for use nf'ater or any other tluid is introduced into the coinpartinent S, which water may then be used in the regular way. lillhen the user has finished with the linger bowl he presses down on the pusher cap 55, which forces down the push button Ltl, and thereby releases the latch hoek a5 troni the latch lug 4t2. By this means the trap door ll is allowed to swing down and the water in the compartment 5d tlows through the orilice 33 into the compartment 59. To fill the compartment 58 the disk 22 is removed :trom the bowl by means of the handle 5G and the trap door eil is swung and locked in its closed position. been emptied et its soiled water the disk 22 is replaced in the hnger bowl, the packing ring 30 making a watertight joint between the said disk and the howl.

Having described .my invention what l desire to secure by Letters Patent and claim is:

1. ln a receptacle of the character described the combination ci. a detachable disk having an orilice, means to make a watertight joint between the disk and the wall oi' the receptacle7 trap door iter said disk and hinged below said oriilice to close the same, and a push button extending through said disk to open said trap door.

2. In a receptacle of the character described the combination et a detachable disk having an orifice, means to make a watertight joint between the disk and the wall ot the receptacle, a trap door :tor said disk and hinged below said orifice to close the same, a spring latch with one end fastened to said disk engaging and locking the trap The linger bowl having till 'iti

door when in its closed position, a push button carried on the spring latch extending through said disk to enable the trap door to be unlocked from the disk.

3. In a receptacle of the character described the combination of a detachable disk having an oriiice, a trap door hinged to the lower face of said disk forA said oriiiee, packing means between the orifice and trap door, a spring latch with one end fastened to the lower face of said disk and maintaining the trap doorin place when in its closed position', a push button on the spring latch extending through an opening in the said disk, and a. flexible pusher cap carried on the disk over said push button to enable the push button to be forced down by exerting pressure on. said cap.

v4. In av receptacle of the character described the combination of a detachable disk having an orifice, a trap door hinged to the lower face of said disk for said orifice, pack ing means between the orifice and trap door, a spring latch with one end fastened to the lower face of said disk and maintaining the trap door in place when in its closed position, a push button on the spriiig latch extending through an opening in the said disk, a flexible pusher cap carried on the disk over said push button to enable the push button to be forced down by exerting pressure on said cap, and a stop bracket extending from the lower face of said disk and under the spring latch to protect the latter.
